# Phase 2: Acceptance Criteria, Test Taxonomy, Observability Spine — Phase Summary

## Objective

Establish the verification infrastructure that Phase 3+ depends on:
1. Formal 39-AC document with unambiguous pass/fail criteria
2. pytest marker taxonomy (6 markers: unit/integration/blackbox/perf/hardware/ac)
3. AC↔test traceability matrix + CI enforcement
4. structlog hot-path spine (10 files, frame_id propagation)
5. Pydantic v2 boundary-log schemas (3 models)

## Plans Completed

| Plan | Name | Key Deliverable |
|------|------|-----------------|
| 02-01 | AC Document Rewrite | 39 formal ACs in `_docs/00_problem/acceptance_criteria.md` |
| 02-02 | (not in scope / skipped) | — |
| 02-03 | Pytest Marker Taxonomy | 6 markers registered, 37 test files decorated |
| 02-04 | AC Traceability Script | `gen_ac_traceability.py`, `AC-TRACEABILITY.md`, `@pytest.mark.ac` on 7 files |
| 02-05 | CI Pipeline + Orphan Reconciliation | `ci.yml` per-marker jobs, `nightly.yml`, 21 orphan ACs annotated |
| 02-06 | structlog Spine | `logging_config.py`, 10 hot-path files switched, frame_id via contextvars |
| 02-07 | Boundary-Log Schemas + Final Gate | `log_schemas.py` (3 models), 20 tests, 236 total passing, gate green |

## Final State

- **Total tests:** 236 passing, 8 skipped (hardware/SITL skips expected)
- **ACs declared:** 39
- **ACs covered by tests:** 15 (non-deferred ACs with ≥1 test)
- **ACs deferred:** 25 (annotated with pending-phase-N in traceability matrix)
- **Hot-path structlog files:** 10
- **Boundary-log schemas:** 3 (MavlinkGpsInputEmitted, ApiRequestCompleted, AnchorDecision)

## Requirements Satisfied

| Req ID | Description | Evidence |
|--------|-------------|----------|
| AC-01 | AC document with formal criteria | 39 ACs in acceptance_criteria.md |
| AC-02 | Every non-deferred AC has ≥1 test | 15 ACs covered, 25 annotated-deferred |
| TEST-01 | pytest marker taxonomy defined | 6 markers in pyproject.toml |
| TEST-02 | Markers applied to all test files | 37 files with module-level pytestmark |
| TEST-03 | CI enforces per-marker lanes | ci.yml: unit/integration/blackbox/perf jobs |
| OBS-01 | structlog spine on hot path | 10 files + boundary schemas |

## Handoff to Phase 3

Phase 3 (Visual Odometry + AnchorVerifier) can begin with:
- Known-good measurement floor: 236 tests, 8 skipped
- AC-2.1b (anchor verification) has schema contract tests; Phase 3 adds integration
- `AnchorDecision` schema ready for Phase 3 AnchorVerifier wiring
- `merge_contextvars` propagation verified; orchestrator binds `frame_id` at frame entry
